18.31.010 Parking requirements.

The minimum off-street parking and loading requirements shall be as follows; provided, that in the DC and DM zones and in the transit-oriented development overlay, the minimum number of spaces shall be reduced by 50 percent:

A. Uses such as banks, professional offices and business offices, retail stores, supermarkets, department stores, personal service shops, medical/dental offices and skating rinks shall provide one parking space per 300 square feet of net leasable area.

B. Uses such as restaurants, nightclubs, taverns and lounges shall provide one parking space per 100 square feet of net leasable area.

C. Shopping centers shall provide one parking space per 250 square feet of net leasable area. For the purpose of this section, a shopping center is defined as a building or buildings designed as a unit containing two or more separate and distinct retail activities within it and utilizing a common parking area.

D. Offices, warehouses and manufacturing establishments shall provide one space per each employee on the largest shift. Parking requirements for retail and service establishments shall be the same as those established in the C-2 district.

E. Mixed Occupancies. In case of two or more uses in the same building, the total requirements for off-street parking facilities shall be the sum of the requirements for the several uses computed separately.

F. Other Uses. For uses not specifically identified in this section, parking shall be provided as specified for the use which, in the opinion of the director of planning and community development, is most similar to the use under consideration.

G. Joint Use. The director of planning and community development may authorize the joint use of parking areas under the following conditions:

1. The uses jointly using parking facilities shall have dissimilar peak hours. The applicant shall show that there is no substantial conflict in the principal operating hours of the two buildings or uses for which joint use of off-street parking facilities is proposed.

2. No more than 50 percent of a use’s parking requirement shall be supplied by a joint use agreement.

3. The building or use for which application is being made shall be located no more than 800 feet from the parking area.

4. A properly drawn legal instrument, executed by the parties concerned, for joint use of the off-street parking area, duly approved as to form and manner of execution by the city attorney, shall be filed with the city engineer.

H. Parking stalls in all areas of the city except the downtown shall be sized as follows:

1. Standard stall: nine feet wide by 18 feet long.

2. Compact stall: eight feet wide by 16 feet long.

3. Parking stalls in the downtown (Figure 1 of the Downtown Design Standards) shall be as follows:

Uses Minimum Width




(1) Residential




(2) Retail and Services Commercial




(3) Banks and Savings and Loan Institutions




(4) Medical Offices




(5) Industrial




(6) Offices




Minimum parking space widths for uses not mentioned shall be determined by the community development director or designee.

4. Whether utilizing standard or compact stalls, overhangs shall not be permitted over sidewalks or required landscaping.

I. Compact stalls shall make up no more than 35 percent of the total minimum parking stalls required. Motorcycle stalls shall make up no more than five percent of the total minimum parking stalls. Compact and motorcycle stalls added together shall make up no more than 40 percent of the total minimum parking stalls. When compact or motorcycle stalls are to be used as part of the minimum required parking stalls, they shall not be located in the area in front of the entrance of the building and shall be placed in the outerlying area of the required parking area. A combination of compact and motorcycle parking stalls in excess of 40 percent of the minimum parking stalls required may be allowed by the planning and community development director if the compact and motorcycle stalls are in excess of the minimum number required and placed in an overflow parking area.

J. For the purpose of this section only, “net leasable area” shall be defined as the interior floor area of a building, excluding stairwells and mechanical areas. (Ord. 1303 §§ 1, 2, 2009; Ord. 1155 § 14, 2005; Ord. 769 § 1, 1998; Ord. 740 § 13, 1997).

18.31.020 Off-street loading.

Off-street loading shall be provided for each use as determined by the director of planning and community development which shall base its decision on the frequency of deliveries to and from the proposed use, traffic patterns in the area, the use to which neighboring properties are put, all to avoid disruption of traffic in the area of the proposed use. (Ord. 740 § 13, 1997).

18.31.030 Performance standards.

The following special requirements and performance standards shall apply to all properties located in the neighborhood commercial; commercial; heavy commercial, warehousing and light industrial; and manufacturing districts.

2. In no event shall radio activity, when measured at such exterior boundaries of the property, be in excess of 2.7 x 100-11 microcuries per milliliter of air at any moment of time. Radio and television transmitters shall be operated at the regularly assigned wave length (or within the authorized tolerances therefor) as assigned thereto by the appropriate governmental agency. Subject to such exception, all electrical and electronic devices and equipment shall be suitably wired, shielded and controlled so that in operation they shall not emit any electrical impulses or waves which will adversely affect the operation and control of any other electrical or electronic devices or equipment.

2. No emission of liquid or solid particles from any chimney or other source shall exceed three-tenths grains per cubic foot of the carrying gas at any point beyond the lot line of the use creating the emission.

E. Heat.

1. No use shall produce heat significantly perceptible beyond its exterior property lines.

F. Glare.

1. No use shall produce a strong dazzling light, or a reflection of a strong dazzling light, beyond its exterior property lines.
